Heat insulation fireproofing honeycomb cement board and preparation method thereof

Abstract

The invention belongs to the technical field of building materials and in particular relates to a heat insulation fireproofing cement board and a preparation method thereof. The cement board is made from master batch and auxiliary materials, wherein the master batch is fast hardening sulphate aluminium cement and ordinary Portland cement; and the auxiliary materials are composed of a waterproofing agent, a brightening agent, a foaming agent, a water reducing agent, an accelerating agent, a moisturizing agent, fibres and water. The fireproofing heat insulation honey cement board provided by the invention has the advantages of good fireproofing thermal insulation property, aging resistance, low deformation coefficient, colour approximating to the colour of a wall body and high bonding strength with the wall body; and the preparation method is simple and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a thermal insulation and fireproof honeycomb cement board and a preparation method thereof. Background technique [0002] Existing thermal insulation materials for exterior walls of buildings often use organic materials such as polystyrene foam plastics and polyurethane stearic foam plastics. Gas is generated, which brings serious difficulties to fire fighting and rescue work, causing casualties and property losses. At the same time, this type of organic thermal insulation material also has the disadvantages of easy aging, poor stability, poor durability, and low bonding strength with the wall. In recent years, frequent building fires have made people put forward higher requirements for the fireproof performance of thermal insulation materials. Inorganic thermal insulation materials have good fireproof performance, aging resistance, small deformation coefficient and a...
